This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding population demography and dispersal of species at risk is integral for evaluating population viability, identifying causes of decline, and assessing the effectiveness of recovery actions. In addition, habitat protection is a key component of endangered species conservation, but critical habitat designations are often based on limited data. In chapter one, I estimated juvenile daily apparent survival, dispersal distance and orientation over four summer and fall periods. In chapter two, I estimated the extent of year-round critical habitat using radio telemetry data combined with a summary of distance data from past studies that tracked movements in other periods of the annual cycle. Collectively, this work fills key gaps in our understanding of the ecology of A. jeffersonianum and their unisexual dependents, highlights key differences between bisexuals and unisexuals, and indicates that the critical habitat area currently defined by the existing regulatory framework in Canada protects insufficient habitat.

This book was released on 2019 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful reproduction in salamanders is driven by behavioral, environmental, and temporal interactions among adults. While much of our understanding of salamander mating systems is based upon either courtship behavior of both sexes or aspects of female choice, the decisions made by males regarding where to place spermatophores is much less quantified. In this study, we mapped male spermatophore placement in the spotted salamander (Ambystoma maculatum) with respect to ecological and spatial locations within a vernal pool complex in Charles City County, Virginia. The overall goal was to use the spatial and ecological placement of spermatophores to determine if individuals deposit spermatophores randomly within the vernal pool or if males exhibited specific preferences for deposition. Using comprehensive surveys of the vernal pools and individual spermatophores within a 0.5m2 grid and terrestrial LIDAR, a total of 218 spermatophores were identified and mapped. We repeated these surveys for two successive breeding seasons. Placement occurred at an intermediate depth and an intermediate distance to the edge. Males also preferred to place spermatophores on leaf substrate as opposed to sticks or conifer needles. The physical placement of spermatophores exhibited autocorrelation in space during single reproductive events as well as across breeding seasons. These results suggest that males actively select for specific locations within a pool for spermatophore placement-a proverbial Goldilocks zone-which may be consistent with increased reproductive success. This information is key to understanding salamander mating system parameters in this species and may contribute to developing more effective management strategies.

Download or read book Amphibians of Ohio written by Ralph A. Pfingsten and published by . This book was released on 2013 with total page 928 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Ohio's resident amphibians currently include 25 species and subspecies of salamanders, a complex of unisexual ambystomatid salamanders, and 14 species of frogs and toads. Existing, comprehensive works of amphibians for Ohio are dated and out-of-print. Given this deficiency, and pressured by recent survey and monitoring activity and current research needs, the decision to produce a comprehensive book about Ohio's amphibians, which this volume represents, quickly followed. Focusing on verifiable information about the amphibian species of Ohio, the core of this tome is comprised of 37 chapters, organized by sections on salamanders and on frogs and toads, covering all amphibians in Ohio that have been documented and vouchered. Preceding these taxonomic, species-oriented chapters are sections on the history of herpetological work in Ohio, a summary of the Ohio environment in which its amphibian species exist, informative introductions to amphibian systematics, brief summaries of the two groups, and keys to adult and larval stages. Following the species accounts are sections on potential occurences in Ohio; on species ranking based on conservation status and knowledge; on amphibian conservation; on amphibian distribution; on environmental applications; and, a summary. Completing the book are two appendices involving field and vouchering/documentation techniques, a glossary, a combined and comprehensive listing of cited literature, and an index. This book is both scientifically accurate and written in a style suitable for the complete spectrum of individuals and entities who are professionally or casually involved or interested in amphibians"--Abstract, page iii.
